Servicing a Bosch Gen 2 Centerdrive Electric Bike Motor – Inside of a Bosch Mid-Drive

In this video a certified Bosch technician removes the second generation mid-drive motor from a Haibike Xduro RX electric bike. To complete this service you will need a lock ring tool (with a half inch drive and adapter) as well as a chain whip and T15 torx driver. The Bosch system can use three cog sizes including 20 tooth for small wheel and 18 or 15 tooth for a mountain bike wheel. The cogs are build by each manufacturer and the Haibike cog has a chain guide built in. The exterior plastic casing of the motor is mainly cosmetic but it does serve as a skid plate as well. This service would be done to install a light kit, deal with a speed sensor issue or replace the entire Centerdrive. From front to back on the left side of the motor are the HMI (Human Machine Interface) Cable, Headlight and Rear light Cable, Speed Sensor Cable and Power Cable. The motor itself weighs ~5.5 lbs. The Bosch Powerpack 400 weighs ~8.8 pounds. Bolts inside are torqued down at ~30 Nm. The new Bosch CX motor weighs 200 grams less and will not require a plastic cover so it will appear smaller visually and allow more clearance for suspension travel.
